SALT LAKE CITY, UTAH—A rock art panel in Utah’s Nine Mile Canyon has been defaced with the initials “JMN” and the date, May 25, 2014. The writing appears in the dark patina next to the prehistoric image known as the Pregnant Buffalo. Two local property owners spotted the graffiti and witnessed two people leaving the scene shortly after the panel was inspected by Jerry D. Spangler, executive director of the Colorado Plateau Archaeological Alliance. “Each act of vandalism is a selfish disregard of the aesthetic, spiritual and scientific values that constitute our collective past. These sites are non-renewable resources, and damage done can never be completely repaired,” Spangler explained to Deseret News.
